Effectiveness of BIC/FTC/TAF was high among HIV late presenters starting ART.

BIC/FTC/TAF also demonstrated a good safety and tolerability profile in this setting.

Among people starting ART with AIDS, BIC/FTC/TAF performance was even higher.

The efficacy of BIC/FTC/TAF in HIV late presenters initiating antiretroviral therapy (ART) has not been sufficiently evaluated.

The aim of this study was to assess the effectiveness and tolerability of BIC/FTC/TAF compared to other first-line antiretroviral regimens in treatment-naïve adult individuals from the CoRIS Cohort starting ART with CD4 counts <200 cells/mm3 and/or AIDS-defining conditions between January 1st 2019 and November 30th 2020. Logistic regression models were used to estimate odds ratios (ORs) of association between initial regimen and achievement of viral suppression (VS) (primary objective), defined as HIV RNA <50 cop/mL, and immunological recovery (IR) (secondary objective), defined as CD4 count >200 cells/mm3, at weeks 24 and 48 after initiation of ART.

We evaluated 314 individuals (84.7% men, median age 40 years). Of them, 158 initiated with BIC/FTC/TAF. At inclusion, 117 had an AIDS-defining condition. In multivariable analyses, individuals with AIDS-defining conditions initiating ART with BIC/FTC/TAF achieved higher rates of VS at 24 weeks than other regimens (aOR: 0.2; 95% CI: 0.06–0.64) and, at 48 weeks, than DTG/ABC/3TC (aOR: 0.06; 95% CI: 0.01–0.76) and DTG + TDF/3TC (aOR: 0.2; 95% CI: 0.47–0.9). No other differences in VS or IR were observed. At 24 and 48 weeks after ART initiation, treatment discontinuations were lower with BIC/FTC/TAF than with other regimens (3.2% and 7.6% vs. 24.4% and 37.8%, respectively; P < 0.005).

Our results suggest that BIC/FTC/TAF could be a preferred regimen as initial therapy in HIV late presenters because of its high effectiveness and good tolerability.
